breast cancer and resistance exercise program

Conditions: Breast Cancer; Resistance Training

Summary: the goal of the study is to test the feasibility and acceptability of a supervised, online-delivered, individualized, physical activity program in a sample of post-active treatment breast cancer survivors. the proposed intervention will use a 2-arm randomized controlled trial study design to compare a 12-week resistance-based physical activity program to an attention control (i.e., printed individualized physical activity program) group on feasibility, acceptability and changes in strength as measured by 10 repetition maximum (10rm). both groups will wear accelerometers. the main hypothesis is that participants randomized to the intervention arm will rate the online-delivered physical activity program as feasible and acceptable compared to attention control participants. the overall rationale is that delivering a physical activity intervention online may increase uptake of the intervention, which may lead to maintained physical activity behavior and associated health benefits. the primary outcomes are feasibility as measured by participant retention and acceptability as measured by adherence to physical activity program (recorded by physical activity log). secondary outcomes include changes in strength as measured by 10rm, objectively measured physical activity levels as measured by the accelerometer, satisfaction, physical functioning and health-related quality of life. additionally, a select number of participants will be invited for an interview to talk about their experiences in the program, motivation and barriers to exercise. interview description: participants will complete one-on-one interviews with the pi or research staff over videoconferencing software (rutgers zoom). the interview will be 45 to 60 minutes in duration and audio recorded using the "record meeting" function. prior to the interview, participants will consent to being audio recorded. the recording will be stored on box (a hipaa compliant cloud drive). a transcript of the audio will be generated using the "audio transcript" function on rutgers zoom and transcribed by a third party to ensure accuracy.

the project will use a 2-arm randomized controlled trial study. the intervention will include a 12, weekly, supervised, online-delivered, individualized resistance-based exercise program. the attention control arm will include a printed, individualized resistance-based physical activity program. a total of 50 breast cancer survivors will be recruited from rutgers cancer institute of new jersey (cinj) and randomized to one of two study arms. the intervention arm will test the feasibility and acceptability of the intervention compared to the control arm, which will receive a printed or digital copy of an individualized physical activity program. participants from both arms will receive an accelerometer (actigraph gt3x+), resistance bands (theraband®), and additional free weights (if required). outcome measures will be assessed at baseline (pre-intervention), week 12 (post-intervention) and week 24 (follow-up). data collection will occur both in-person and online. data will be both objective (10rm, functional strength, physical activity measured by accelerometers, physical function assessments, and attendance) and subjective (self-reported physical activity program adherence, satisfaction, physical activity levels, health-related quality of life, and exercise and barrier self-efficacy). additionally, participants will complete one-on-one interviews with the pi or research staff over videoconferencing software (rutgers zoom). the interview will be 45 to 60 minutes in duration and participants will be asked to discuss their experiences in the program.
